The seasonal distribution and density of larval fish are important factors affecting the potential entrainment of ichthyoplankton species. An assessment of entrainment of larval fish and eggs and their potential effect on an adjacent fish community was required by regulatory agencies. A year-long study was conducted to document the ichthyoplankton community (eggs and larval stages) of the Thames River adjacent to a saltwater intake. Individuals were identified using standard microscopic and photographic techniques for identification. In the lower Thames River, winter flounder (Pseudopleuronectes americanus), a commercially and recreationally important species, was the primary species of investigation. Seasonal distribution of common species encountered and the generalized approach assessing standardized adult equivalent losses will be discussed.

Northumberland Strait (you crossed over it to get here) is a stressed coastal ecosystem; however, a dearth of quantitative studies has resulted in the lack of baseline data against which to test for improvements or decline in ecosystem health. An ambitious four-year research plan (The Northumberland Strait Ecosystems Research Initiative) has been developed to quantify the structure of this highly dynamic water body beginning with identification of water masses and currents and progressing through to fishes and large decapod crustaceans. In the first phase, numerical models of movements of water and sediments are being developed and tested empirically using newly-developed MAPs technology. Aggregate biomass models (e.g., spatially explicit nutrient and biomass pools, size-spectra, biodiversity measures, pelagic and demersal food web) are being developed to describe the mass and flux of nutrients and energy in the Strait for both the pelagic and demersal energy cycles (including potential coupling). The eventual goal is to develop full ecosystem-level models (e.g., mass-balance and nutrient loading/flux) for use in integrated management programs based largely on the information gathered in this project
